Specification of Letters Patent.

Patented Nov. 8, 1921.

Application filed November 8, 1920. Serial No. 422,582.

To all whom it may concern:

Be it known that I, GEORGE E. VON Horr- MANN, a citizen of the United States, residing at Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Scrapers, of which the following is a specification.

This invention relates more particularly to scrapers or devices for cleaning mud or dirt from boots or shoes.

The objects of this invention are to provide an improved cleaning device or apparatus for cleaning mud from shoes; to provide a scraper having resilient cleaning members; to provide a scraper or cleaning device having springs for engagement with the boots or shoes; to provide a scraper which is adapted to be used on automobiles; and in general to provide such an improved construction as will be described more fully hereinafter.

In the accompanying drawings showing a, preferred form of my invention;

Figure 1 is a side view.

Fig. 2 is a plan view with parts broken away.

Fig. 3 is an end view.

My improved scraper or cleaning device comprises in general, resilient cleaning members with a. frame for supporting the Same. As shown in these drawings 4 repre sents a frame upon which is mounted longitudinally arranged springs 5. The frame 4 may be made in any suitable form but is preferably made so that it is adjustable. Such adjustment is readily provided by having a fixed base member 6 with an upwardly projecting arm 7 and an adjustable base member 8 with an upwardly projecting arm 9. An adjusting screw 10 passes through a threaded hole 11. in the arm 9 and has a shouldered projection 12 which engages with a hole 13 in the arm 7. The base portions 6 and 8 are secured to a floor or running board 14 by means of screws 15.

The base portion 8 is provided with slots 16 for such the longitudinal movement of the arm 9 for adjustment.

The ends of the springs 5 may be secured screws and in order to permit to the arms in any suitable manner as by having rings or hooks 17 which engage with holes in the arms. The drawing shows four of these longitudinal springs but any suitable nnmber may be used and these springs may be made of wire of any suitable cross section either round or angular.

The longitudinal springs will ordinarily serve for cleaning purposes but in some instances I provide projections 18 on the end arms or brackets for supporting transverse springs 19 which are useful for cleaning the sides of the shoes.

This device is exceedingly eflicient for removing dirt, mud or the like from boots or shoes as the springs or yielding members act rapidly in loosening such material from the shoes. Furthermore the vibration or springing of the members tends to clean themselves and also to throw the dirt away from the scraper. This device may be used for doorsteps, automobile running boards,-

or other places where desirable.

Having thus described my invention, what I claim and desire to secure by Letters Patent is;

1. In a cleaner, the combination of an arms having projections at the tops thereof,

and transverse springs, carried by said projections.

3. In a cleaner, the combination of a base having two upwardly projecting arms, means for adjusting one of said arms, and springs extending longitudinally of said base and having their ends connected to said arms.

GEORGE E. VON HOFFMANN.
